Greenline Offers Responsible Power Packs, Eliminating the Need for Generators

The Slovenian builder of efficient motor yachts from 39 to 58 feet announced this week that is is offering a new option that will eliminate the need for generators on all of their diesel-powered boats. A genset has been an integral part of traditional diesel technology but Greenline now has a better solution.

On all of their models with diesel engines, they now are adding the Responsible Power Pack that includes huge solar arrays and large lithium battery banks that replace the need for a separate generator. When the boat is at anchor, the panels charge the batteries with enough amps to run all of the boat’s electric devices, including air conditioning.

When underway using diesel diesel power, the engine then charges the battery bank via high powered alternators. With nine hours of motoring the system delivers up to 48 hours of battery reserve.

“For conventional yachts, eliminating the generator is nothing short of revolutionary,” said Vladimir Zinchenko, owner of Greenline Yachts. “There is barely a yacht on the market in Greenline’s class of length and luxury that is capable of doing this. My mission has always been to further the concept of responsible yachting, and this shift towards using high-powered alternators and batteries will save tons of CO2 emissions.”

Here is a case study that Greenline provided with their announcement.

Take the Greenline 45, the Slovenian yard’s best-selling model. In the past, this yacht has needed an 11kW generator to cover hotel loads, consuming 4 liters of fuel per hour. It often runs constantly in order to power the air conditioning unit, amounting to consumption of nearly 200 liters over a 48-hour period at anchor.

Fitted with the new Responsible Power Pack, it would require just 9 hours of motoring totally recharge the 34.2kWh batteries, giving emissions-free power onboard for more than 48 hours. To produce its 6kW of power, the alternator places additional load on the engine which does marginally increase fuel consumption for that period. However, when compared side by side, the new system slashes the emissions of covering hotel loads by up to 88 per cent.

The figures are unequivocal,” said Chief Commercial Officer Luca Raumland. “Our Responsible Power Pack can eliminate a staggering amount of the carbon emissions associated with running a yacht at anchor. By tapping the engine’s spare power when the yacht is under way, we can make non-hybrid models almost as efficient to operate as their hybrid alternatives. In fact, with careful use of the aircon, the solar panels fitted as standard to every yacht can fully replenish the batteries during the day and keep you emissions-free at anchor indefinitely.
